Abstract

5-Oxo derivatives of three new isomeric pyridopyrrolo[1,2-a]pyrimidines were synthesized from the corresponding carbalkoxy 2- or 3-[N-pyrrolo]pyridines. These were transformed into the corresponding hydrazides and further to acylazides which decomposed into acylnitrenes followed by insertion into C-H bond with ring closure.
